Magico M7 (sæt)

Magico M7 er en firevejsgulvhøjttaler, der tilbyder en forbløffende ydeevne. Med den nyeste Magico-enhedsteknologi, et organisk formet kulfiber- og aluminiumskabinet samt det nyeste elliptiske symmetri-delefilter er M7 en tour de force inden for avanceret højttalerteknik.

M7 blev udtænkt af grundlægger og administrerende direktør Alon Wolf som en mere tilgængelig version af den semi-aktive M9. Magicos ingeniørteam fik til opgave at skabe den helt passive M7, der sikrer en lydkvalitet, der aldrig før er opnået i en højttaler af dens størrelse.

Magico udnyttede værktøjer som en Klippel Near-Field Scanner og et Polytec Laser Doppler vibrometer, blandt mange andre avancerede værktøjer, sammen med to årtiers designerfaring med at skabe branchens mest avancerede højttalere. I den sidste udviklingsfase i Magico-lytterummet viste M7 sig at være langt mere end summen af dens betydelige materialeregning.

Tweeter & Midrange

The M7 uses the tweeter designed for the M9. This high-frequency 28mm driver utilizes a beryllium diaphragm with optimized geometry. The diaphragm is then diamond coated using a chemical vapor-deposition process to push the beryllium substrate ever closer to the theoretical ideal.

Magico engineers created a new neodymium-based motor system that results in the lowest distortion possible, massive dynamic capability, and even greater power handling than previous designs. Lastly, the acoustical performance of the back chamber was improved with careful FEA modeling.

The 5” pure midrange driver in the M7 features a Gen 8 Nano-Tec cone formed of an aluminum-honeycomb core sandwiched with outer and inner layers of graphene-infused carbon fiber. The advanced cone is supported by a newly designed basket assembly and an innovative foam surround, the latter to help achieve ideal cone/surround integration.

The result is faster settling time and impressively low distortion. The all-new underhung neodymium-based motor system uses two extra-large magnets to facilitate a super-stabilized magnetic field. A pure copper pole cap minimizes eddy currents and maximizes efficiency. This new development in midrange driver technology sets a new benchmark for measured performance in both the frequency and time domains. This is the highest-performing 5” midrange ever developed.

Midbass & Bass

The M7’s 9” midbass driver uses a newly designed basket assembly along with Magico’s Gen 8 Nano-Tec cone, consisting of an aluminum-honeycomb core sandwiched with outer and inner layers of graphene-infused carbon fiber. This drive unit is equipped with a 127mm voice coil and an underhung neodymium-based motor system using dual extra-large magnets. The vented pure titanium voice-coil former enables +/-13mm of stable movement. This high-sensitivity driver is capable of output of 120dB @ 1m in its band pass. By separating the power region from the lower octaves, the M7’s midbass section brings music to life in ways unmatched by any other design save for the M9.

The M7’s new 12” bass driver uses a newly designed basket assembly and a Gen 8 Magico Nano-Tec cone, which includes an aluminum-honeycomb core sandwiched with outer and inner layers of graphene-strengthened carbon fiber.

This drive unit has a 127mm voice coil, an underhung neodymium-based motor system using an extra-large magnet, and a top magnet to get a super-stabilized magnetic field. Parts include a huge copper cap and a vented titanium voice-coil former, contributing to +/-15mm of stable movement at very high sensitivity. A new composite-material spider ensures great heat dissipation with no rocking distortion. This driver is capable of 120dB SPL @ 25Hz measured at 1m. 

Enclosure

Magico’s continued research and development in eliminating cabinet vibration and stored energy has realized numerous ground-breaking advancements. The M7’s enclosure design is simply not possible using common sheet-stock construction methods.

The M7’s enclosure begins with a monocoque carbon-fiber shell conceived using Finite Element Analysis (FEA) modeling. A multiply 6061-T6 aluminum front baffle with constrained-layer damping using aerospace composites is affixed to an aluminum rear baffle with front-to-back tensioning rods.

The result is a cabinet that produces negligible internal resonances, enabling a minimal amount of damping—again, a design optimized conceptually and then tested until perfected. The baffle shape was refined until almost no diffraction effects were measurable. The M7’s overall structure results in maximum strength on every axis, with extreme stiffness and rigidity along with minimal energy storage. The M7 possesses, essentially, a silent enclosure.

Crossover

Magico’s Elliptical Symmetry Crossover (ESXO) is used in its most advanced and costliest form in the M7.

The four-way network contains components from Mundorf of Germany and Duelund Coherent Audio of Denmark—only the finest of their types and values were selected. The M7’s ESXO crossover perfectly integrates the six drive units into a virtual point source—the six drivers sounding as one complete whole.

A bespoke support system developed specifically for the M7 uses MPOD technology in order to provide an absolutely stable footprint while eliminating noise and achieving perfect coupling to the floor. In addition, the M7’s support system offers a subtle visual contrast to the carbon-fiber-and-aluminum cabinetry.

Lastly, on the rear of each M7 is a chrome plate with Alon Wolf’s signature. This signals Wolf’s personal endorsement of every M7 that leaves the Magico factory.
